    摘要: The present invention relates to hydraulically bonded cement compositions and methods. More particularly, the present invention is directed to novel compositions and methods of hydrating hydraulic cement without mechanical mixing of the cement and water. The present invention includes materials prepared by manipulating under pressure powdered hydraulic cement compositions using known or novel powder packing, casting, or expanding techniques, such that air within the powdered hydraulic cement is substantially removed while the cement is formed into a self-supporting near net final position. Thereafter, the formed hydraulic cement is hydrated without mechanical mixing of the cement and water.
